摘要： The invention relates to a device (1) for the variable setting of the control times of gas-exchange valves of an internal combustion engine, with a driving element (12), with a driven element (8) and with an adjusting gear (11) designed as a triple-shaft gear, the driving element (12) being mounted rotatably with respect to the driven element (8) on the latter or on the camshaft (9). The relative phase position of the driven element (8) with respect to the driving element (12) can be selectively varied or held by means of the adjusting gear (11). According to the invention, it is proposed to mount the driving element (12) on the driven element (8) by means of rolling bearings (19, 21).Radial and/or axial forces can thereby be supported in an optimized way in terms of friction, as a result of which the efficiency of the device (1) is increased.

The camshaft adjuster is provided with a triple-shaft gear drive having a driving pinion that is fixed to the crankshaft, an output part which is fixed to the camshaft, and an adjusting shaft. The adjusting shaft is connected to a motor shaft (5, 5′, 5″) of an electric adjusting motor that is provided as a pancake motor (1, 1′, 1″, 1′″) including a pancake (3, 3′, 3″) and a stator (15, 15′, 15″, 15′″) which is disposed in a housing (8, 8′, 8″) with an associated cover (9, 9′, 9″). In order to create a camshaft adjuster that is inexpensive to produce and operate, the pancake motor (1, 1′, 1″, 1′″) is configured as a brushless DC motor (BLDC motor) whose housing (8, 8′, 8″) and cover (9, 9′, 9″) are arranged to be fixed to the cylinder head and whose motor shaft (5, 5′, 5″) is connected to the adjusting shaft by a releasable coupling.

摘要： The invention concerns a rotary piston adjuster for adjusting the angular position of the camshaft of an internal combustion engine, said adjuster comprising an outer rotor having at least one hydraulic chamber, and an inner rotor comprising at least one pivoting vane that can pivot hydraulically in the hydraulic chamber between a retard stop position and an advance stop position. A locking device suitable for detachably connecting the outer and inner rotors to each other and at least one compression spring acting in opposition to the frictional torque of the camshaft are arranged between the two rotors. A liberal design of the compression spring and a low-wear operation with this spring are enabled by the fact that the compression spring (27, 27′) is arranged in an attachment (4) that is connected to the rotary piston adjuster, and the components of the attachment have a wear-resistant configuration and support the compression spring (27, 27′) at least pointwise over its entire length.

摘要： A machine (1) has a rotor (3) located so that it can rotate in a housing (2). The rotor is located at least partly in fluid, such as coolant. To provide a machine which has lower losses with a higher cooling capacity, the housing pressure can be reduced so that the fluid transitions into the two-phase range. In one embodiment, the housing pressure can be reduced by a suction device (7).

摘要： A control structure for the adjusting motor of an electric camshaft adjuster in an internal combustion engine is provided. The control structure includes a controller which processes measuring signals of the internal combustion engine to control data for the adjusting motor. A controller which has meaningful values for the adjusted setpoint rotational speed of the adjusting motor, even when the input differential signal has a zero value, is obtained by applying the signal of an uncontrolled rotational speed to the output signal of a controlled setpoint rotational speed.
